This tutorial is for the person who understands HTML but doesn’t know much about PHP. One of PHP’s greatest attributes is that it’s a freely distributed open-source language, so there’s all kinds of excellent reference material about it out there, which means that once you understand the basics, it’s easy to find the materials that you need to push your skills.

If you need to parse HTML, regular expressions aren't the way to go. In this tutorial, you'll learn how to use an open source, easily learned parser, to read, modify, and spit back out HTML from external sources.
